RANGER CHARGING SYSTEM

1998 Ford F-250

1998 Ford Ranger, 4.0 V6, 80,000 miles
Charging system quits when gets to about 2500 rpm. Volt meter drops and Batt light on dash comes on. At Idle and lower RPM, system is normal. What could be the problem?
Thanks, -Fred

Sounds like it could just be a worn out set of brushes in the alt. Or a worn out rectifier in the alt.

Check all the connections for corrosion or burning. If none, use a volt meter on the main power wire of the alt itself and check for the voltage to drop. If yes. Probably worn out.

Have it checked out by a pro to make sure.
